This program tests the assertion that if there aren't any more queued signals
for the selected signal, then the pending indication of that signal is
reset.
Steps:
- Register for myhandler to be called when SIGTOTEST is called, and make
sure SA_SIGINFO is set.
- Block signal SIGTOTEST from the process.
- Using sigqueue(), send NUMCALLS instances of SIGTOTEST to the current
process.
- Call sigwaitinfo() NUMCALLS times, and verify that the pending indication
for signal SIGTOTEST has been reset.
